Spark Test Remove spark plug clean with solvent & wire brush. Reconnect plug wire and let plug hang close to engine. Pull the starter rope and look for spark. Dim lighting makes it easier to see.
If no spark replace plug and try again. Check off/on switch and wire coming from coil. If still no spark replace coil. (Older saws clean and adjust points first).
If saw runs but, not on gas in tank, check gas tank for old gas. Empty old gas and, look for syrup in the bottom of the tank, if present clean thoroughly. Use carburetor cleaner, gas and a brush that can reach in and not melt. Try to start with fresh gas mix. If it doesn’t start check and replace fuel line and pick-up. If it still doesn’t start remove carburetor and check manifold boot (tube between carburetor and engine).
Replace if needed and try to start. If it still doesn’t start remove carburetor,disassemble and clean thoroughly. You may have to soak in Simple-Green overnight. Try not to get solvent or carburetor cleaner on gaskets.
Check gaskets. Diaphragm gasket should be smooth and puffy not wrinkled or wilted.
If in doubt replace. Carburetor kits are around $8-$15 and include all gaskets, needle and spring. Reassemble (making sure all gaskets are positioned properly) and try to start. If it still doesn’t start replace carburetor. This how-to works with a Husqvarna, Husky, Jonsered, Poulan, McCulloch, Craftsman, Homelite, Echo chainsaws as well as a Stihl 009, 009L,011, 011T,012, 017, 018, 018C, 019, 019T, 020, 020AV, 020T, 021, 023, 024, 025, 026, 026 PRO, 028, 029, 034, 036, 036 PRO, 036 QS II, 039, 044, 046M, 066M, 088M, MS170, MS180C, MS191T, MS192T, MS200, MS200T, MS210, MS250, MS260, MS260 PRO, MS270, MS280, MS290, MS310, MS360, MS360 PRO, MS360 QS II, MS361, MS390, MS440, MS460, MS660, MS880, HT100, HT101, HT70, HT75. First thing I’d do is slightly loosen the gas cap.
Does it run properly when you do that? If so, your problem is most likely a plugged tank vent – the saw runs fine until it creates so much vacuum in the tank that it can’t suck fuel anymore. Then change the gas filter on the end of suction hose in gas tank. You can fish it out with a piece of wire. If that doesn’t help, then check gas line and impulse hose closely for small cracks. Next take off the muffler check to see if the piston is scored from the starter fluid (bad idea use 50:1). If none of that helps, it has carb problems:debris in needle valve, harden diaphragm.
I would rebuild the carburetor, the rubber diaphragm gets hard over time. Also replace the fuel hose, and impulse hose.
Disassemble the carb, and thoroughly clean it out, the inlet screen and the passage below the screen, you will have to remove the needle/lever from the other side to blow it out.Replace the diaphram. You may be flooding it, in the cold choked position. This is all the way down on the master control.
Take spark plug out and pull cord a few times in with master control in off. It only takes one correctly pulled pull then up to second from bottom is to start engine and warm up a few seconds. Make sure your break is ON. Full throttle.

Blip the throttle. To auto go into Runyon, then pull chain break off. Now start and stop in upper positioning of master control rest of your day. I rarely need to go to starting positions needing throttle pressed to get to, lowest two. Maybe second from bottom if engine gets cold, in very cold weather.
From here, be careful in lowest master control possition, as smaller Stihl tend to not pop as larger ones and hard to tell the engine turning indicating switch up one. I just bought a used Stihl ms170 at a pawn shop. I got a good deal on it but it wont start. I replaced the plug, air filter and fuel filter. It still didn’t start. I tried to find a carb rebuild kit but found out a whole new carb was only $35 so I bought it and replaced it and it still don’t start.
I made sure it is getting spark and getting gas. I cleaned off the screen in the muffler also. I noticed at the top of this page it asks about picking the saw up with pull cord, well the cord comes out before I can get the saw off the ground. Does this mean the compression is bad?? I have a Stihl 025 and no oil is exiting the oil port at the chain/bar.
Initial indication was a dry chain. Took clutch / cover off and found wire detached from worm gear that turns oil pump. Purchase a new one and reinstalled. Still no oil.
Disassembled and found oil under clutch cover or in that area, but still not get to bar and chain. Pulled oil pump and blew out line to bar/chain with air and seemed clear. Pump appears to be functioning fine. Pump alignment to supply port looks good as well.
Still no oil to chain. Purchased a new pump, installed – still no oil to chain. I have a Sthl MS 170 chainsawIt was starting hard and curtting poorlyWhile I had the chain bar off to get the chain sharpened, I took the cover offI noted a black wire with a metal piece on the end that was loose and there seems to be no place to attach it. I also noted the spark plug was loose.
I tightened it and the saw starts much better even tho the black wire isn’t attached to anythingBut with the chain bar off, I note the motor seems to be smoking and running very hot. What would cause the motor to run hot and where does the little black wire go? I had the same starting issue with my brand new MS250. This is what I did in the end.
I had the chainsaw on the ground with my right foot supporting the saw through the handle, and pulling the cord with my left. 1st set it to full choke, do 2 good pulls. Then half choke, 1 good pull. And here’s the tricky part.
Set it to ‘run’ position and slightly cock your right foot so its depressing the throttle. You may have to cluck the safety first, but once its clicked your foot will be able to pull the trigger. Make sure your.comfortable and put more emphasis on holding the saw!!!! Do a few.good.pulls and it’ll go.

I’ve never had to do this again – it was only from brand new. I have a STHIL MS 290 that appearsto have too much compression. It rips the cord out of my handvery difficult.Only used to cut the winters firewood. Have had it to several STHIL dealers but they could not find a problem. The problem is still there and there is only a few hours on the saw. When I first got the saw it started really well.If this problem cannot be fixed, I will have to get rid of the saw.
Hoping you can help solve the problem because I really liked the saw in the beginning. I have an MS250 that’s worked well for dozens of hours this year. Today, after adjusting the chain tension and operating the saw for a couple of minutes, the chain tightened on the bar to the point that it wouldn’t turn. After taking off the sprocket cover, I could barely turn the wheel (by hand) to loosen the chain. This same sequence happened several times.
I noticed when I was sawing that the chain seemed to “grab” the wood rather than cutting smoothly like it usually does. The chain is newly sharpened and the bar is straight.
Chain oil is at least leaving the reservoir at the right rate. The thing that’s really got me stumped is that the chain noticeably tightens with use rather than becoming looser. Why does my farm boss 290 chain keep over tightening and binding so bad that it stalls out and then won’t restart??
I have removed the bar and chain and it runs well, I have put it back together and readjusted the tension several times making sure the tensioner pin was aligned properly in the hole and securely tightened down but yet by the time I have cut halfway thru a log the same thing keeps happening time and time again!?! On some attempts it even happened before I could begin cutting. What is going on?
Wrong info for starting!I’m a Stihl tech, When I started a year ago we had a mass amount of new returns,couldn’t start them. I was told the same stupid thing!
